65amps pedals are very well built, but a bit pricey even for what they are. Colour Boost is one of the best treble boosters I've tried. Colour Fuzz sounds good but probably not that good as you may expect from that price tag. I have both pedals. Never tried Colour Bender.
I'd say Analogman Beano Boost, Sun Face, Lumpy's Tone Shop Tone Bender may assure a better value. But 65amps pedals are the quality stuff anyway.
They are definitely expensive. I got my Colour Boost brand new for $50 off the normal sticker price or else may may have went a different route. That being said, I'm in love with it and am glad to own it.
